What does the 'fire triangle' represent?

The 'fire triangle' represents a model that illustrates the three essential elements required for fire to occur: heat, fuel, and oxygen. Each corner of the triangle corresponds to one of these elements, and the fire can only exist when all three are present. Understanding this concept is crucial for fire safety, as eliminating any one of these components can extinguish a fire. This knowledge can be applied in various scenarios, such as in firefighting techniques, fire prevention strategies, and safety training.
